Stall Prevention (Overvoltage)

What does Stall prevention (overvoltage) mean?

The overvoltage stall prevention function has been activated, often occurring during regenerative braking or deceleration. This indicates that the DC bus voltage within the inverter is rising to an excessively high level, threatening to damage internal components. This protection ensures the inverter remains within safe operating voltage limits.

Complete Troubleshooting Guide

1. 1

   Set the deceleration time (Pr. 8) longer to reduce the rate of regenerative energy return to the DC bus.
